Measures reported by CtxXcXDServersTest

Server OS Machines are VMs or physical machines based on the Windows Server operating system used for delivering applications or hosted shared desktops to users.

This test auto-discovers the Server OS Machines in the site and reports the session load on, resource usage of, and current state of each machine. This way, administrators can quickly identify machines that are experiencing heavy load and those that are consuming resources abnormally.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Power_state Indicates the current power state of this server OS machine.   The values this measure can report and their corresponding numeric values are listed in then table below:

Measure Value Numeric Value
Unknown 0
Unavailable 1
Off 2
On 3
Suspended 4
Turning on 5
Turning Off 6
Suspending 7
Resuming 8
Unmanaged 9

Note:

By default, this measure reports the Measure Values in the table above to indicate the power state of a server OS machine. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents only.

Maintenance_mode Indicates whether/not this machine is in the maintenance mode currently.   The values this measure can report and their corresponding numeric values are listed in the table below:

Measure Value Numeric Value
Off 0
On 1

Note:

By default, this measure reports the Measure Values in the table above to indicate whether/not a server OS machine is in the maintenance mode. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents only.

Pending_image_update Indicates whether/not image updates are pending on this machine.   The values this measure can report and their corresponding numeric values are listed in then table below:

Measure Value Numeric Value
No 0
Yes 1

Note:

By default, this measure reports the Measure Values in the table above to indicate whether/not image updates are pending on this server OS machine. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents only.

Is_physical Indicates whether this server OS machine is a physical or virtual machine.   The values this measure can report and their corresponding numeric values are listed in then table below:

Measure Value Numeric Value
No 0
Yes 1

Note:

By default, this measure reports the Measure Values in the table above to indicate whether/not a server OS machine is a physical machine. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents only.

Total_sessions Indicates the total number of user sessions on this server OS machine. Number This is a good indicator of the current session load on a server OS machine. Compare the value of this measure across machines to know which machine is overloaded with sessions.
Load_evaluator_index Indicates the load evaluator index of this machine. Percent A server's load index may be the aggregate of:

  • Various computer performance counter based metrics, namely CPU, Memory and Disk Usage
  • Session Count

It is designed to indicate how suitable a XenApp Worker is to receive a new user session. It is the Delivery Controller's responsibility to calculate the load index based on the aggregate of the normalized load rule indexes generated by the various load rules. As only the Delivery Controller can determine the session load, a server's overall load index is calculated on the Delivery Controller and not the Virtual Delivery Agent.

By comparing the value of this measure across server OS machines, you can figure out whether or not load is uniformly balanced across all servers in the site.

Cpu Indicates the CPU load evaluator index of this server OS machine. Percent A high value is indicative of excessive CPU usage by the machine over time.
Memory Indicates the memory load evaluator index of this server OS machine. Percent A high value is indicative of excessive memory usage by the machine over time.
Disk Indicates the disk load evaluator index of this server OS machine. Percent A high value is indicative of excessive disk usage by the machine over time.
Session_count Indicates the session count load evaluator index of this server OS machine. Percent A high value indicates that the machine has been consistently handling many user sessions.
Poweredon_desktops Indicates the number of desktops that are currently powered on. Number  
Suspended_desktops Indicates the number of desktops that are currently in the Suspended state. Number  
Poweredoff_desktops Indicates the number of desktops that are currently powered off. Number  
Unavailable_desktops Indicates the number of desktops that are currently Unavailable. Number  
Resuming_machines Indicates the number of server OS machines that are currently in the Resume state. Number  
Unmanaged_machines Indicates the number of server OS machines that are currently in the Unmanaged state. Number  
Total_machines Indicates the total number of server OS machines in this group. Number
